MPTP-induced SN neuron loss in WT and CP KO mice is ameliorated with CP or DFP. 5-month-old WT and CP KO mice were administered MPTP (50 mg/kg, I.P.) and euthanized 21 days after. A sub-set of WT and CP KO mice were treated with dosing regimens of CP or DFP during the experimental period. (a) RHS SN was microdissected and iron was measured by ICP-MS. (b) LHS midbrain was sectioned and Nissl stained neurons were counted by stereology. (c) Liver was harvested and measured for iron by ICP-MS. Data are mean ± std error. ‘n’ is represented in graph columns. *p < 0.05, ***p < 0.001 as indicated. ^p < 0.05, ^^p < 0.01, ^^^p < 0.001 relative to control of the same genotype.
